Water: Humidity or moisture level is directly proportion to the watering cycle. In summer, its best to water the orchids every week or every 7-9 days. In winter, watering cycle should be anywhere between every two weeks or every 12-15 days.
A beautiful species like Orchid requires a unique watering method, which is: place your orchid pot in a water tub and allow it to sip water for about 5 to 7 mins! This is the best method to water orchids, as it will not harm the leaves, which is the usual case if you water them from top.
Orchid is a delicate plant, so you do want to avoid over watering it which will lead to declining growth. Orchids that are ready to bloom may shed their buds as a result of overwatering.
Many new growers worry over the thought of over-watering the plant and as a result end up dehydrating it. Consequently, the plant shrivels down its buds as the leaves starts absorbing water from the buds in the process of self-preservation.
